Design and Analysis of Novel Nursing Transformative Assistive Robot Comprised of Transfer and Omnidirectional Carrying

Abstract

In this paper, we present design and analysis of a novel nursing lift and wheelchair which can run towards omnidirectional on the ground. The proposed assistive robot provides a power assist function for transfer aid system with hoisting, and also an omnidirectional motion function using DDSS (Differential Drive Steering System). By transforming the length of Boom, Shaft, and Leg Parts, novel power assist robot can easily transfer the person from wheelchair to bed, and vice versa, and furthermore can carry the person as a wheelchair. To show the usefulness of the proposed robot, several experiments with a series of nursing operation have been done in the present research.
